The first meeting with Aizen *a bit spoiler*

i've just started reading Bleach all over again, and in the last chepter of VOL.3 there was someone speaking with the Grand Fisher and turning it into it new version of hollow(that we saw in the last chepters), i think it was Aizen, but it's hard to deside... what do you think?

You could see an Arrancar sitting there. Most likely, it was D-Roy (or whatever the official spelling is). Although not exactly the same art, he sure looks like him. (probably just an early Arrancar design from Kubo)

I'd like to die with the songs I love stuck in my head. I hope to make the most of these hollow bones we become.
I raise a toast to the the souls that sang all along. I've been gathering friends to just to make some sounds,
before the ship goes down, I've been making amends by making the rounds before the whole world ends
